Open season for our notion-building pollies
Since the Finkel review was announced it has been open season for notion building in the energy space. While Malcolm has been spruiking Snowy 2.zero pumped hydro, Craig has been promising death by renewables, quite literally. Josh seems to be for just about everything, besides Labor state governments of course, and reckons we are on track to meet Paris commitments. Barnaby, true to form, is backing coal, and presumably thinks Paris will take care of itself, while Electricity Bill is keeping mum.
The one I like the best, but really hasn’t been nailed quite the way I thought it should, is Tony’s call for nuclear subs. Imagine, our first truly dispatchable power system, capable of delivering a few hundred megawatts just about anywhere you need it. “Float and plug” - just what we need to shore up our fragile energy system. A tour of dispatch last year including Tasmania from January through June, South Australia June through November, and then on to Queensland for the summer would have been a nice little money spinner for the Navy, worth around quarter of a billion dollars on the energy markets. And that doesn’t include offsets, such as the purported $44 million Tasmanian government spent on diesel gensets. Could it be our best notion yet for meeting Paris?
It goes without saying that our political masters don’t need much provocation to indulge in a bit of notion building. After all, it is what they do best.
But, in case you are wondering why this sudden release of energy, it might be useful to reflect on some recent analyses that paint a truly disturbing picture for our energy sector.
The first comes from the European Commission’s latest electricity market update, providing the comparison of wholesale electricity prices shown below.
International wholesale prices as adapted from Figure 33 in the European Commission’s Quarterly report on European electricity markets Q1 2017. Average prices for the 4th quarter of 2014, 3rd quarter 2015, and the first quarter of 2017, are referenced as a percentage of Australian prices. Figure 33, Quarterly report on European electricity markets Q1 2017, https://ec.europa.eu/energy/sites/ener/files/documents/quarterly_report_on_european_electricity_markets_q1_2017.pdfAs recently as three years ago our electricity wholesale prices were low by any measure. In fact according to the EC’s analysis,
our market prices then briefly dipped below those in the US. Then, ours were just 20% of the Japanese price.
How times have changed.
According to the EC’s latest analysis our prices tracked pretty closely with the US until the second half of 2015. It seems things to start going awry just about when Josh was received the poison chalice as Minister for Energy and Resources.
Six quarters later and the EC now estimates that for Quarter 1 this year our prices were a staggering 400% higher than in the US.
This last quarter we even managed to top Japan, which is some achievement considering that across the quarter we exported some20 million tonnes of our thermal coal and over half a million tonnes of LNG to help them sure up a power system still reverberating from the shock waves of Fukushima. That’s about half as much thermal coal as used to power our system.
The second comes from BP’s latest Statistical Review of World Energy released in June, which provides national figures for all things related to energy production and consumption, including sector wide emissions.
According to BP’s latest figures, our energy sector produced about 409 million tonnes of CO2 in 2016. That amounts to 16.7 tonnes for every Australian. On a per capita basis, that puts our energy sector a touch above the next most emissions intensive economy in the developed world - the US at 16.5 tonnes. Even Canada, which has a resource based economy more comparable to our own, gets away with only 14.6 tonnes per person.

Emission data from BP’s Statisical review of World Energy. GDP and population data from IMF. Dots show 2009, in the wake of the GFC.Worryingly, relative to 2005 levels our energy sector emissions are up about 10%, which stands in stark contrast to most other advanced economies, and especially the US, down 12% over the same interval.
National energy sector emissions for select advanced economies, relative to 2005 levels, using data from BP’s latest Statistical Review of World Energy released in June. Australia’s Paris commitment is to reduce national emissions to 26-28 per cent on 2005 levels by 2030. Note that for Australia energy sector emissions (including transport and power) account for about 2/3 the total emissions.So the notion that we are on track to meet Paris is, at best, notional.
To achieve such extraordinary wholesale price outcomes, one might imagine something remarkable had happened to our energy system since 2014. Our Coal-cons such as Craig Kelly would believe it is because our power system is groaning under the weight of renewable production.
But perhaps it the absence of renewables. Or maybe it is both, peskily masked in a cloak of invisibility. Check out the figure below, which shows our electricity production by key fuel group (coal, gas and renewables) over the period since our power prices have risen from the lowest to highest on the international pecking order.

RE (renewables) includes hydro, wind and large scale solar and biomass, but does not include rooftop PV which is not dipsatched onto the market.Can you determine a trend that could account for anything? I’m damned if I can.
And that in itself is sure to be worry enough to keep it open season on notion building for a long time to come.
For those interested, some more detailed discussion of the crisis besetting the National Electricity Market (NEM) in eastern Australia can be found in my Anatomy of an Energy Crisis series, Part 1, Part 2 & Part 3.

The four-year treasure hunt for the hoodwinker sunfish
Sunfish are famous for looking odd. They are the largest bony fish in the world, can grow to over 3 metres in length and weigh up to 2 tonnes, and look a little bit like a suitcase with wings.
But when I began my PhD doing population studies on sunfish off Bali in Indonesia, I didn’t expect to discover an entirely new species. What began as something of a side project turned into a four-year treasure hunt, flying thousands of kilometres to track down evidence with the help of dozens of people.
As part of my PhD research, I analysed more than 150 samples of sunfish DNA. Genetic sequencing turned up four distinct species: Masturus lanceolatus, Mola mola, Mola ramsayi and a fourth that didn’t fit with any known species.
A new species had been hiding in plain sight for centuries, which is why we ended up calling it Mola tecta: the hoodwinker sunfish. But back then, in 2013, we didn’t even know what they looked like; all we had were skin samples containing the mysterious DNA.
The hoodwinker sunfish grows to at least 2.4 metres long, with a distinctive ‘backfold’ of smooth skin separating the back fin into two. Illustration by Michelle Freeborn, Wellington Museum Te Papa Tongarewa. Going on the huntThe next step was trying to figure out what these fish might look like. Superficially, all sunfish look the same (that is, slightly strange). Their bodies are flat and rigid, except for their fins; they don’t have a tail; and as they grow bigger they usually develop odd bumps on their head, chin and nose.
So I started looking at pictures of sunfish, especially on social media, searching for something different. I also spent a long time establishing a network of people across Australia and New Zealand who could alert me whenever a sunfish was found.
I finally got a break in 2014. Observers from New Zealand and Australian fisheries were sending me pictures of sunfish they found out at sea, usually just a fin in the water. But on one occasion they hauled a tiny fish on board to free it from a fishing line, and got a brilliant photo of the whole thing along with a genetic sample.
This fish had a little structure on its back fin that I’d never seen on a sunfish before. Just as I was wondering if this was a characteristic of the species, I hit the jackpot when four fish were stranded in one go on the same beach in New Zealand.
I flew down to Christchurch, landed at night and drove out on to the beach. I saw my first hoodwinker sunfish in the headlights of the car – it was incredibly exciting. This changed everything, because now we knew what we were looking for.
A hoodwinker sunfish off the coast of Chile. César Villarroel, ExploraSub What is the hoodwinker?Unravelling this mystery has been a huge puzzle. Sunfish are huge, largely solitary and fairly elusive, so you can’t just go out and sample a heap of them to study. You have to fly thousands of kilometres when there’s a stranding and hope it’s the right puzzle piece you’re looking for.
However, by looking at stranded specimens, photos and museum collections, and by verifying specimens genetically, we have been able to describe this species very accurately.
We found enough fish to describe this species on a size spectrum of 50cm to nearly 2.5m. Unlike the other species, they don’t develop lumps and bumps as they grow; instead their body dimensions stay pretty much the same between juveniles and adults. Their back fin is separated into an upper and lower part, with a small flexible piece of skin, which we have termed the “back-fold”, connecting the halves.
We don’t know exactly what their range is, but it seems to be the colder parts of the Southern Hemisphere. We’ve found them all around New Zealand (mostly around the South Island), off Tasmania, South Australia, Victoria and New South Wales (Australia), South Africa and southern Chile.
Sunfish aren’t particularly rare, but it’s tricky to study them as they simply live in parts of the ocean most humans don’t go. They dive hundreds of metres to feed, and then rise to the surface to bask in the sun on their sides (hence their name).
This habit of diving and rising throughout the day means they can be caught by a range of fishing gear, including tuna longlines or in drift gillnets and midwater trawls. Fishers have been turning them up for centuries. When we looked back through the literature to see if this species had been described before, we found sunfish in books that included mermen and unicorns, and one of the first written mentions comes from Pliny the Elder.
This Chilean video identifies the fish as the common sunfish (Mola mola), but they have the separated back fin of the hoodwinker sunfish (Mola tecta). A sunny communityOf course, this discovery didn’t happen in isolation. A group of researchers from Japan first identified the possibility of a new species from a single skin sample about 10 years ago. We were able to work with two sunfish experts from the University of Tokyo and the University of Hiroshima to describe the hoodwinker, and to compare it in detail with the other two Mola species.
We also collaborated with geneticists from the Gemmell Lab at the University of Otago and expert taxonomists from the Wellington Museum Te Papa Tongarewa, who prepared and now house the “holotype”, which is the name-bearing specimen and official representative of Mola tecta.
Fisheries observers from the Australian Fisheries Management Authority and the New Zealand Ministry of Primary Industries have sent me around 120 samples from sunfish they sampled while on patrols, which was the basis for the initial study.
Finally, we’ve had invaluable support from the public. On one occasion, a gentleman and his young daughter even drove out on a quad bike to a remote beach just to gather samples. (I do believe sunfish bring out the best in people.)
After four years of work – and the help of many people – it’s great to be able to finally share the hoodwinker sunfish with the world!
